Introduction: Several Uses for Old Cans

have any cans lying around? then don't just throw them away! recycle them!

I will let you see some awesome ways to use your cans!

Step 1: Make a Fire

yes that's right! make a fire!

this is because the back of a can is a perfect parabola, that means you can focus light with it!

you will need:
a piece of chocolate
can
piece of paper
sunny day

step 1.
rub the chocolate over the bottom of the can until it reflects good

step 2. go outside and focus the sun with it on your piece of paper

step 3.
have fun

Step 2: Popcorn Machine

what you need:
tape
tealight
nails
can
vegetable oil
corn
knife

step 1
make the can; draw a triangle on the can like in the picture and cut it out like I did

step 2
make the holder. get the tealight and tape the 4 nails around it

step 3
put the mixture in. 2 teaspoons of corn and 1 teaspoon of oil

step 4
the rig; put the can on top of your nails

step 5
the popcorn; light wait add salt and enjoy!

Step 3: Make It a Target

this is actually quite familiar with those airsofters out there...
but for those who don't know:

put a can on some spot at about chest height

shoot it off

    bb guns and airsoft are about the same if you shoot someone with a gas airsoft gun it has about the same power as a bb gun

    BB guns shoot metal bb's and a typically more powerful. airsoft use plastic BB's.

    airsoft guns shoot plastic bbs. and BB guns shoot metal ones but if you have a air cannon you cann shoot any thing you want, like a stapler, cellphone, or a jackknife.

    it makes popcorn! Wow! Im telling mom about this, i hope she'll like it

    i dont really know the difference between airsoft and bb but they are about the same

    There's no way that this Instructible legitimately got something like 46 votes. There's only eight comments and less than 500 views. This can't be right. Not bashing the author here, I'm just confused...

    Ah, its someone voting with lots of accounts. If you notice who voted for him, the account names are all random numbers.

    but everyone got like 40 votes i guess there is some1 who wants to screw up this contest

    Right now, nowhere. To prevent people from trying to skew the top votes list with fake votes, we've hidden it away. We'd prefer that people focus on the quality of each instructable than if people are cheating.

    but i wanna brag by my friends how much votes i have =[
    could you please make something that you can see your own votes?
